1.Purpose and Product Usage:

The Blind Spot Information System (BLIS) warns the rider against collisions that may occur

due to a lane change maneuver. BLIS is intended to supplement the vehicle’s rear-view

mirrors, not eliminate the need for such mirrors. BLIS is intended to detect vehicles to the

rear and sides of the subject vehicle and warn the rider if a lane change is not

recommended. BLIS is not meant to encourage aggressive driving and the absence of a

warning will not guarantee that the rider can safely make a lane change maneuver.

1.1 Detailed Radar Description

The BLIS radar tracking system operates within the 76-81 GHz frequency-band or its

subsets (pertaining to FCC part 95, subpart M), and used for short-range vehicular radar

target tracking. The radar is based on Vayyar’s VYYR7202 RF SoC.

The radar subassembly is a multi-antenna MIMO-radars, transmitting reference

signals,receiving the radio signals reflected from the objects at the positions to be

determined, and comparing the reflected signals with the reference signals.

The information is gathered by transmitting the reference signals from an array of antennas,

concurrently collecting the signals by an array of receiving antennas, and comparing them to

reference signals in order to determine the distance and direction to the objects of interest.

The signal generation, recording and processing is performed by a Vayyar’s VYYR7202

multi channel RF transceiver SoC.

The recorded signals are processed either on a DSP embedded within the radar VYYR7202

chip or on a hosting device, to obtain spatial information about the environment, detect

objects in the vicinity of the radar, and characterize their position and various properties

(velocity, shape, object classification etc).

1.1.1 Frequency Range and Modulation

The radar module is operating within the 76-81GHz frequency-band, where the certified

profile operates near 77.2-78.2GHz. The radar signals used can either be an FMCW or a

stepped-frequency CW modulated signals.
